Studying has both costs and benefits. If you continue tostudy (e.g., for a test) for as long as the marginal benefitsof studying are greater than the marginal costs, and youstop studying when the two are equal, will your actionbe consistent with having maximized the net benefits ofstudying? Explain your answer.

(1) Sergei had to decide among watching a two-hour movie with a cost of $20, buying a book to read for $10 that would take about four hours to read, and going to a three-hour concert for $30. If he considers the benefit of each situation to be proportional to the amount of time, with a value of about $50 per hour, what is the opportunity cost of the best decision A) $190 B)$150 C)$120 D)$80

Kim and Abby are sisters who share a room. Their room can easily get messy, and their parents are always telling them to clean it up. Here are the costs and benefits to both Kim and Abby, of taking time to clean their room:  If both Kim and Abby clean, they each spend  two hours and get a clean room.  If Kim decides not to clean and Abby does all the cleaning, then Abby spends 10 hours cleaning (Kim spends 0) but Abby is exhausted.  The same would occur for Kim if Abby decided not to clean - Kim spends 10 hours and becomes exhausted.  If both girls decide not to clean, they both have a dirty room. a.  What is the best outcome for Kim and Abby? What is the worst outcome? (It may help you to construct a prisoner's dilemma table) b. Unfortunately, we know that the optimal outcome will most likely not happen, and that the worst outcome will probably be chosen instead.  Explain what it is about Kim's and Abby's reasoning that will lead them both to choose the worst outcome.

Would the opportunity cost be a benefit to UPS shipping or a benefit to UPS international shipping for this example? “To begin, I began selling prints of my pictures in 2019 throughout 2020. It's now closed. USPS and UPS were the options I had during this period to ship out orders. Smaller or lighter packages were more expensive to ship with UPS, but USPS provided a low-cost alternative. UPS ships more than 220 internationally, whereas; USPS is strict about shipping to specific international destinations. I have chosen USPS over UPS; by doing this, orders were delivered on time and without damage by the United States Postal Service.”

Question 3 ( A B C D E Production Point Mountain Bikes a) straight-line; increase Ob) straight-line; decrease Oc) curved; decrease 0 30 50 60 65 d) curved; increase Beer 100 90 70 40 Refer to the table above. if you were to plot the points, then this would be a PPF, so when you try to produce 5 more mountain bikes from 60 to 65, the opportunity cost of beer will at a higher rate. 0

Jane enrolled in an online class to learn a new language. The online class will cost Jane $150. After enrolling in the class, Jane needs to consider how many hours she is willing to spend on learning a new language. For the first hour, Jane will get an incremental benefit of $85. Subsequently, she will only get incremental benefits of $74 from the second hour, $55 from the third, $30 from the fourth and $15 from the fifth. The cost to Jane, mainly due to fatigue and boredom, is $6 for the first hour, $12 for the second hour, $19 for the third hour, $29 for the fourth hour and $40 for the fifth hour. Using marginal analysis, Jane should spend how many hours learning?. The maximum surplus for Jane, from spending the number of hours learning which you found in part b, is $. Answer to the nearest whole number (with no decimal places).

Your total benefits from spending time with your spouse are shown in the following table. Hours per Day 0 Total Benefit 0 20 38 54 68 80 90 98 104 Alternatively, you have the option of working as many hours as you want, earning $11 per hour. Assume this is the next best use of your time. Use the marginal principle to find your optimal number f hours to spend with your spouse per day. The optimal amount of time for you spend with your spouse is hours per day. (Enter your response as an integer.)

Assume that the price per hamburger is $2.50. The incremental value to you of each hamburger is described in the table below. If you are seeking to maximize total net gains from hamburgers, how many hamburgers should you purchase?      Pairs of jeans                  Marginal Benefit                 1                                   $8.00                 2                                   $6.00                 3                                   $4.00                 4                                   $2.00                        5                                   $0.00 Group of answer choices 3 2 4 5 1
